Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

log Pow  > 5.7 (No information is given on pH and temperature)

Key value for chemical safety assessment

Additional information

The partition coefficient of the substance fatty acids, C8 -10, mixed esters with adipic acid and trimethylolpropane (CAS 95912 -89 -3) was determined according to EU Method A.8 with HPLC method. The reference item is listed as reference item with the second highest log pow=5.7, DDT (log pow=6.2) was not used due to toxicological reasons; therefore the partition coefficient is deduced to be log pow > 5.7. The partition coefficient determined by QSAR calculation with KOWWIN (v1.68) for the single components log Pow =10.64 - 13.59 is reported with restrictions, due to the fact that this substance is long chain fatty acid ester which exceeds the applicability domain of KOWWIN. Therefore the partition coefficient of the substance, deduced to be > 10, is supporting.
